ELECTRIC SIGN.

SPECIFICATION forming part of Letters Patent no. 73 7;129,dated August 25,1903. Application filed Ma 1a, 1903.- Serial No. 167,648. (No model.)

To all whom it may concern:

Be it known that I, THOMAS E. MURRAY,

I of the city, county, and State of New York,

' have invented a new and-useful-Improvement in Electric Signs, of which the following is a. specification.

The invention relates to an electric sign whereon a suitable inscription is illuminated by adjacent glow-lamps.

The invention consists 1n theconstruction of the sign-board-and the arrangement there- .with of said lamps in order to secure better illumination of said inscription.

In the accompanying drawings, Figure l is suitable way. Surrounding said platoon plates is a hollow frame 2, the sides 3 of which adjacent to said plate are to be inclined at an acute angle to the plane of the sign-plate. Said frame maybe made in two parts 4 and 5, one part being integral with each of the two parallel plates-1, connected together by bolts passing through flanges 6. Inthe inclined sides of the frame 2-are openings to receive sockets 7 of any suitable construc-" tion, in which sockets are held the glow-lamps 8. Said lamps are to be connected in circuit in the usual way. An eye 9 for suspending the sign maybe secured to the flanges 6, as

two subscribing witnesses.

' shown. The lamps may be disposed on one side or on both faces of the sign, and the contour of the frame is preferably polygonal.

- This construction is simple and light. The

supply-conductors for. the lamps (indicated by dotted lines 10) are concealed within the hollow frame. The advantage of placing the lamps at an acute angle to the-plane surface 7 to be illuminated by them is that a much better degree of illumination is obtained than when they project outward at right angles to said surface.

I claim- 1. A sign-plate, a frame surrounding the same having a side adjacent to said plate 'inclined at an acute angle to the plane thereof, and electric glow-lamps disposed on said in clined side and projecting therefrom.

. 2. A sign-plate, a hollow frame surrounding the same having a side adjacent to said plate inclined at an acute angle to the plane thereof, electric glow-lamps disposed on said.

inclined side and projecting therefrom, and

supply-conductors for said lamps within said hollow frame.

3. A sign-plate, a frame surrounding the same having a side adjacent to said plate inclined at an acute angle to the plane thereof, and electric glow-lamps disposed on said inclined side and projecting therefrom.

'In testimony whereof I have signed my name to this specification in the presence of THOMAS E. MURRAY.
